application ed May 12, 1915. Serial No. 27,557.

.To all vlc/tom. maz/ concern Be it known that l, HENRY E'Donnnea, a citizen of the United States, residing at Cannon Falls, in the county ot' Goodhue and State of Minnesota, have invented certain new and vuset'nl improvements in Demountable lhee nime; and do hereby declare the following to be av full, clear, and exact description 'oi theinvention, such as Wienable others skilledl in the art to which'it sipgiertinsto make and use. the saine. u

Ely if- 'entice relates to improvements in demountable wheel rims; and, to this end, it consists of the novel devices and combina-` tions of devices hereinafter described and defined in the claim.

ln the accompanying illustrate the invention,

drawings, which like characters 1ndicate like parts throughout the several views. y

Referring to the drawings, Figure l is a side elevation of an automobile Wheel having the invention applied thereto Eig. 2 is a transverse section taken on the line m2 9:2 of Fig. l on an enlarged scale; Fig. 3 is a transverse section taken on the line w3 we of Fig. l on an enlarged scale; and, also, showing applied to the demountable rim a tire c: -g Within which is mounted a pneumatic j and, Fig. is a inentalry perspective vier-f oi demountable Wheel rim on an enlarged scale.

The numerals l,

id 3 indicate respectively the wooden fe M the spokes and the hub ot :an automobile Wheel, which may be ci the standard or any desired construction.

ijeinianently secured on the Wooden telly usually by shrinking', is a iellyband 4 raving integrally formed therewith a pluf of circuniierentially spaced. loclr lugs :is shown three, el den'iountable Wheel rim e is implied the telgr band Il and its edges are rolled ou tri/ard. and inward to form cieuchcr flanges 7, adapted to receive" and hold the clencher beads 8 or" a tire casing 9. Within the casing 9 is mounted thecustomary pneumatic inner tube 10.

@n the inner face of the deinountable Wheel rim is circiunterentially extended channel ll, having in one of its sides a plurality of circumferentially spaced entrance pa. ges l2, as shown three. The lock lugs a re arranged to be inserted into the channel ll, through the entrance passages l2, by a lateral movement of the 'deniountable Wheelrini 6 with oil.circuxnerentiuilly spaced lock lugs 13 that 13 correspond engagement with the respective lock lu I are also circurnerentially spaced with ree spect to the entrance passages l2, as best shown in Fig. e. The

number of lock lugs to the number of lock lugs 5, and the circumferentially spacing of the two series isthe saine, so that the lock lugs directly engage the lock lugs 13 in the direction of the forward rotation of the Wheel.

To hold the lock lugs 5 .in contact with the lock lugs 13 and against movement in the direction of the baci-:Ward rotation of the wheel, there is provided a set Sorenr 14. This set screw le is circumferentially spaced from one of the lock lugs 5, a distance sufficient to project back of the lock lug 13 in 5. The set screw 14 has screw-threaded engagementwith a lange nut 15 permanently secured tothe folly l by 'screws 16 passed through the flange of said nut and into the telly l. This set screw 14: also has screwthreaded engagement With a flanged sleeve l set screw'le is arranged to be projected into respect to the telly band, l

the channel 1l through the bottom thereof. Obviously, by turning the set screw7 14: in the proper direction, the inner end thereof may be Withdrawn from the channel 11, so that the lugs 13 may be moved circumferentially in the channel ll, to and from operative positions. A lock nut 18 on the set screw 1 -1 is provided for holding the same against accidental rotation. From the foregoing description, it is evident that the alcove described demountable Wheel rim may be very quickly and easily applied to the-fellyband, or removed therefrom. The invention is also, extremely simple, of comparatively small cost to manutfactureend with few parts to get out of adjustment.

lWhat I claim is:

The combination With a demountable Wheel rimhaving a, circumferential channel with a plurality of lateral entrance passaid channel, with circumferentally spaced respect tosaidentrance passages, of a felly band having a plurality of circumfeien-- and arranged to be projected into said ehannel, back of one of the lock lugs 0n the demountable rim to hold the lock lugs on said demountable rim in engagement with the look lugs' lon the felly band, the inner` end of said set screw being engageable with the bottom of the channel in said demountable rim, and having a look nut by means of which it may be locked in such engagement.

In testimony whereof I affix my signature in presence of two Witnesses.

HENRY E. DOEBLER.
